Apex
Apex is a lap-compare app for track days. It imports telemetry from TrackAddict and GoPro, so you can line your laps up against friends.
It includes a theoretical best lap, a corner-by-corner breakdown, driver profiles and leaderboards, shareable lap links, and video sync. Weather and tire notes stay with the session.
It’s built with Next.js and Supabase, and it runs on Vercel.
